Grade YH21CT Super-ferritic stainless steel
Producing advantage: Equipped with large-scale, advanced and high
efficient equipments, we can produce a series of super ferritic
stainless steel product is in different grades and specifications,
and meet the requirements of market.
Quality of products: The process which use hot metal as main part
of materials to produce super ferritic stainless steel can reduce
the unnecessary elements to lowest level. Using VOD decarburization
and denitrifying process can get the lower content of carbon and
Application of Super Ferritic Stainless Steel Industry
The industry of automobile exhausting system: We have established
long term cooperation with end users and service centers which work
at automobile exhausting tubes and pressed parts.

Welding Properties and Notice:
- Low carbon and Nitrigon, Titanium and Niobium added, high
corrosion-resisted performance on welding parts.
- Difficult for Fusion wedding and etter for filler wire welding.
- Low thermal expansion coefficient-high heat conduction and small
deformation after welding comparing with 304.
- Try to avoid heat imputing, otherwise result in bigger crystalline
grain and influent the toughness of the plate.
- Gas protection: Argon protection is needed to avoid surface
oxidization and nitrizing.
- To Avoid the contanmination of grease, otherwise carburization will
- Better to use 309L or higher grade welding rod.
Research and Development Target
400 series will be our research and developing target in future.
Supper ferritic stainless steel will be hightlight, and as the
substitute of 304 for our aim on the direction of economic research
and developing. Realize 439 and 443 product seriation, enlarge the
application of decorationg industry such ad the decoration of
outside roof and curtain wall. Develop the high-chromium ferritic
stainless steel such as 445, 446M and so on to improve the
application of 400 series.
- To provide consumers with the personalized designs on composition,
propertiesproperty, packing, coil weight and quality certificate.
- Technical support to customers in material selection fabrication.
- Accurate and prompt delivery
- Response to customer’s claim within 24 hours.
